bug#55499: [PATCH 0/3] Make 'manifest' files more compact |

Hello,
These patches implement what you suggested on IRC: not repeating
entire manifest entries and their propagated inputs. This has a
dramatic impact on the size of the ‘manifest’ file and on the memory
and processing time to read it for the the use case you gave.
The second patch goes a tiny bit further by making the ‘search-paths’
and ‘propagated-inputs’ fields optional, shaving another ~10% on the
size of ‘manifest’ in this example.
The second patch should be squashed with the first one (so we don’t
bump version formats a second time and duplicate code). It’s kinda
optional because it doesn’t bring much compared to the first patch and
causes a bit of extra complexity, but maybe it’s still worth keeping?
Could you try this on your larger use cases and tell me how it goes?
Thanks,
Ludo’.

tests: Augment profile collision test.
profiles: Do not repeat entries in 'manifest' file.
squash! profiles: Make all entry fields optional.
